The Edison cell chargers that powered lights and radios used mechanical
rectifiers. the read was tuned like a tuning fork and magnetized with a
magnet. As the AC powered a solinoid coil the read would vibrate on/off at
the power frequency producing 1/2 wave DC. A sync. rotery gap should do the
same job if timed correctly.
